polka-bearer-token

Bearer token middleware for Polka. Ported from express-bearer-token.

Tested with Polka@next.

Install

npm install polka-bearer-token

yarn add polka-bearer-token

pnpm add polka-bearer-token

Usage

import polka from "polka";
import bearerToken from "polka-bearer-token";

const app = polka()
  .use(bearerToken())
  .use((req, res, next) => {
    console.log(req.token);
    next();
  })
  .listen(8000);

Per RFC6750 this module will attempt to extract a bearer token from a request from these locations:

• The key access_token in the request body.
• The key access_token in the request params.
• The value from the header Authorization: Bearer <token>.
• (Optional) Get a token from cookies header with key access_token.

If a token is found, it will be stored on req.token. If one has been provided in more than one location, this will abort the request immediately by sending code 400 (per RFC6750).

API

bearerToken(options?): Polka.Middleware

options

Type: object

For APIs which are not compliant with RFC6750, the key for the token in each location is customizable.

bodyKey

Type: string
Default: "access_token"

The key that will be used to find the token in the request body.

queryKey

Type: string
Default: "access_token"

The key that will be used to find the token in the request params.

headerKey

Type: string
Default: "Bearer"

The value that will be used to find the token in the request header. Case-insensitive.

cookie

Type: boolean | object
Default: false

Set to enable cookie parsing. If the cookie is signed, a secret must be set.

Setting this to true uses the default { key: "access_token" }.

[!WARNING] By NOT setting signed: true, you are accepting a non-signed cookie and an attacker might spoof the cookies. Use signed cookies when possible.

signed

Type: boolean
